Parts for your 2017 Nissan Pathfinder-Sump plug washers

2017 Nissan Pathfinder sump plug washers

Yes, the 2017 Nissan Pathfinder (R52, 3.5‑litre V6) uses a sump plug washer. Nissan’s Factory Service Manual for the R52 (section LU – Engine Lubrication) specifies a gasket/washer for the drain plug and instructs replacement whenever the plug is removed. The Nissan parts catalogue (FAST) lists a 14 mm crush-type drain plug gasket for the model, commonly referenced under Nissan part numbers 11026-01M02 and 11026-JA00A used across many late‑model Nissans. Those technical sources confirm the washer is relevant and fitted from factory.

On this Pathfinder, the sump plug washer is a soft aluminium crush gasket that sits between the drain bolt head and the sump. When the plug is tightened, the washer deforms slightly to create a reliable seal, stopping annoying drips and messy weeps. It’s a simple, inexpensive part that does a critical job—keeping the engine oil where it should be and the driveway clean.

Because it’s a crush washer, it’s designed for single use. Each time the oil is changed and the drain plug is removed, the washer should be replaced. Reusing a flattened washer can lead to seepage, which shows up as a damp ring around the plug or spots under the car after parking. For Aussie and Kiwi servicing schedules—often every 10,000 km or 12 months, or more frequently under harsh conditions—popping in a new washer each service is cheap insurance.

• Always fit a new, correct‑size washer (14 mm ID for the Pathfinder) at every oil change.
• Clean the sump sealing face and the plug head before refitting, never stack washers.
• Tighten the drain plug to the factory spec from the Nissan FSM, don’t overtighten.
• Avoid thread tape or sealants—use the proper crush washer to do the sealing.
• Carry a couple of spares, genuine or quality aftermarket equivalents are fine.

If a magnetic or aftermarket drain bolt is installed, it still relies on the same style of crush washer to seal. Orientation isn’t fussy for flat aluminium types, but the mating surfaces must be clean and smooth. A quick post‑service check for any weeping around the plug after the first drive is a smart move.

For part matching, use the VIN with a Nissan parts desk, many listings show 11026-01M02 or 11026-JA00A as suitable for the R52 Pathfinder. Either way, a fresh washer at each service keeps the Pathfinder leak‑free and happy.
